Lady Macbeth helped plan the details of Duncan's assassination and pushed Macbeth, when he seemed to be wavering, to "screw (his) courage to the sticking place" and get on with it. However, though she egged him on, Macbeth allowed himself to be persuaded. Knowing the kind of woman she was, Macbeth need not have communicated the witches' prophesies to her. Perhaps he knew that he might change his mind, and thus ensured that she would prevent him from wavering in his resolve. However, lady Macbeth played no part in planning and executing all the other murders. Macbeth himself was solely responsible for these. Thus it could be said that Lady Macbeth played a part in pushing Macbeth into committing the first murder, but it is Macbeth himself, who remains ultimately responsible for his actions and for their ultimate downfall.
